It's executing a string, so little surprise that it eventually faulted: > echo " 62 63 2f 6c 6f 63 61 6c-65 2f 6c 6d 6f 6e 65 74 61 72 79 2e 63 2c 76 20-31 2e 31 32 2e 32 2e 32" | tr '-' ' ' | sed -e 's/ / 0x/g' | dh | hd 00000000 62 63 2f 6c 6f 63 61 6c 65 2f 6c 6d 6f 6e 65 74 |bc/locale/lmonet| 00000010 61 72 79 2e 63 2c 76 20 31 2e 31 32 2e 32 2e 32 |ary.c,v 1.12.2.2| 00000020 There haven't been a whole lot of changes. My guess would be the recently added smbios support. You can probably just comment out the call to smbios_detect() in sys/boot/i386/loader/main.c as a simple test for that. It could also possibly be the multiple console support in which case it would be easiest to just step your sys/boot tree back using CVS. The good news is that sys/boot is largely self-contained so you can step it back while keeping the rest of the tree up to date for testing purposes at least. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
